On June 30, just two weeks after the facility entered full commercial operation, Mongolian President Ukhnaa Khurelsukh paid an official inspection visit to the Ulaanbaatar Central Sewage Treatment Plant, a flagship infrastructure project constructed by a leading Chinese engineering firm. During his tour, the president walked through the plant’s core treatment facilities, received a comprehensive briefing from project teams on construction timelines, strict technical specifications, and current operational performance, and offered formal recognition of the project’s delivery.
In public remarks following the inspection, Khurelsukh lauded the wastewater treatment facility as a tangible symbol of the deepening comprehensive strategic partnership between China and Mongolia, noting that it stands as a living testament to the warm, longstanding friendship between the two neighboring peoples.
Built by China Railway No 4 Engineering Group Co Ltd (CREC4), the plant officially launched operations on June 15, 2026, as a key bilateral cooperation initiative between the two countries. According to Ni Ming, a project representative from CREC4, the entire development of the facility leveraged Chinese engineering standards and cutting-edge Chinese wastewater treatment technology, tailored to meet Ulaanbaatar’s pressing urban environmental needs.
For years, Ulaanbaatar has grappled with inadequate wastewater infrastructure that strained public health and environmental quality. This new facility addresses a critical gap in the capital city’s public services, while also showcasing the outcomes of practical, mutually beneficial cooperation between China and Mongolia under bilateral partnership frameworks. The project joins a growing roster of cross-border infrastructure initiatives that strengthen people-to-people ties and advance shared development goals between the two neighboring nations.
